A backlight includes a light source and one or more light recycling films. The light source generates light that exits the light source with an angular exit distribution. The light recycling films are oriented in relation to the light source so that the prism peaks of the recycling films are oriented away from the light source. The recycling films have a range of optimal incident angles that allow light to pass through the recycling films without recycling. The components of the light source, the characteristics of the recycling films, or both, are configured to control the overlap between the exit distribution of the light source and the optimal incident angle range of the recycling films.

Systems and methods for controlling backlight output characteristics

A backlight device includes a prism film having a top face on a display panel side and a bottom face opposing the top face, and a reflector plate having a reflection face opposing the bottom face. A prism-like pattern is formed on the top face of the prism film and a scattering pattern is formed on the reflection face of the reflector plate. When a first normal line axis of a slope forming the prism-like pattern and a second normal line axis of one slope forming the scattering pattern are projected on an imaginary plane parallel to the display panel, the projected first and second normal line axes form an acute angle.
